US 6,856,896 B2 · Vehicle recognition support system

Abstract

A vehicle recognition system to enable a two-wheeled vehicle without a navigation system to recognize the position of a traffic intersection and to cause itself to be noticed by other vehicles. The system includes a communication distance measurement modem which receives positional information of a traffic intersection and the current position of a four wheeled vehicle from the four-wheeled vehicle. The vehicle information interface (I/F) collects vehicle velocities, acceleration and deceleration, and mileages and provides them to an electronic control unit (ECU). A differential global positioning system (DGPS) measures the current position based on an electric wave received by a GPS antenna and correction information received by a FM antenna. The ECU determines the presence of another vehicle that the two-wheeled vehicle may intersect, and outputs visual and audio signals to the helmet worn by the driver of the two-wheel vehicle.

Claims14

Dependent claims

A vehicle recognition support system in which each of a plurality of vehicles recognizes a current position of itself, and exchanges said current position by wireless communication with others of the plurality of vehicles,

wherein at least one of the plurality of vehicles is a main vehicle, the system comprising:
a navigation system on the main vehicle for providing map information including positional information of a traffic intersection;
and
means on the main vehicle for transmitting said map information to a sub vehicle via said wireless communication, the sub vehicle lacking its own navigation system for providing said map information.

1 more element

A vehicle recognition support system for a plurality of vehicles capable of wireless communication with each other wherein at least one of the plurality of vehicles is a main vehicle, said main vehicle comprising:

position survey means for determining a current position of said main vehicle;
map information including positional information of a traffic intersection;
means for extracting said positional information of the traffic intersection existing in a prescribed range in a direction of travel from said map information;
and
means for issuing said current position of said main vehicle and said positional information of the traffic intersection to a sub vehicle via said wireless communication, said sub vehicle lacking its own position survey means for determining said current position.
